  * Where H is the head with tail length 4, it checks the + area to see if it can hit any of the edges, then it is called safe, or picks the biggest area if none safe.
- * .tmp bit values: 0 tail , 1 head , 2 no tail growth , 4-8 is direction , 16 is wait flag
+ * .tmp bit values: 1st head, 2nd no tail growth, 3rd wait flag, 4th Nodie, 5th Dying, 6th & 7th is direction, 8th - 16th hue
  * .tmp2 is tail length (gets longer every few hundred frames)
  * .life is the timer that kills the end of the tail (the head uses life for how often it grows longer)
+ * .ctype Contains the colour, lost on save, regenerated using hue tmp (bits 7 - 16)
